What it will cost me? Real money or some virtual money from the game that called coppers? I don't know what coppers are but I think that coppers are the money that you gain from Trackmania races. Also where I can see how many coppers I have? And how many coppers they will cost me? Coppers are gained by races and they are used only for car skins,tracks etc?? Also mind that I have the Trackmania Nations Forever and NOT the Trackmania United.
